Hi Ben,
maybe there is also a difference between SNAPSHOT and versioned SNAPSHOT
jars. I.e. if your project A has a currentVersion like '1.1-SNAPSHOT' and
you create the jar with 'maven jar:install' you'll have a
'a-1.1-SNAPSHOT.jar' in your local repository. In this case if a project B
has a dependency like this
<dependency>
<groupId>a</groupId>
<artifactId>a</artifactId>
<version>1.1-SNAPSHOT</version>
</dependency>
a new version in your local repository gets overriden by an older version in
the remote repository.
However, if you install your jar with 'maven jar:install-snapshot' you'll
find a 'a-SNAPSHOT.jar' and a 'a-YYYYMMDD.HHMMSS.jar' in your local
repository. Maybe in this case if project B has a dependency like this
<dependency>
<groupId>a</groupId>
<artifactId>a</artifactId>
<version>SNAPSHOT</version>
</dependency>
the local 'a-SNAPSHOT.jar' doesn't get overridden by an older remote
version.
Note, that the Maven project and the Maven-Plugin uses the first way of
creating SNAPSHOT jars.
It would be great, if a SNAPSHOT download would check the date in bith
cases.
